Application filed Octoberv 12, 1926 "Serial 1 10. 141,160.

The invention contemplates novel operating means for a fly screen, or like part, for a window or other opening to admit of the screen being manipulated by one hand, both 5 when placing it in position or removing it .fl'OIIl the window,thereby leaving the other hand free to support the sash, .ifnecessary, or for any purpose whatsoever. i

The invention is particularly advantageous in connection with windows having non-counterbalanced sliding sashes and adapted to receive'adjustable fiy screens, since one hand may be engaged in hold ng 'the sash while the other hand is occupied in manipulating the screen, either to place it in position or remove it from the window, asrequired.

The invention provides in combination with a sectional liy screen, operating means whereby the screen may be simultaneously manipulated and adjusted by one hand, said means including a pivoted member mounted upon one section of the screen and a link forming connecting means between the pivoted member and the'other section of the screen;

The invention furthermore contemplates lock means in connection with the screen operating means for holding the same and the screen in the required adjusted position.

, While the drawingsjillustrate a preferred [embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design maybe varied'and such other changes in the minor details of construction maybe resorted to within the scope of the invention as claimed, without. departing from the spirit thereof; j q For a full understanding of the invention and the merits thereoni'eference is to be had to the following description and the drawings hereto attached, in which Figure 1 is a perspective view of a fly screen provided with operating means embodying the invention, the ClOttGddlIlGS 111-.

Corresponding and like parts are referred to in the following descriptionand designated in the several views of the drawings by like reference characters.

any determinate way.

The fiy screen illustrated is of the type comprising sliding sections, and adapted to be extended to fit different sizes of windows, as well as to providefor holding the screen in place and admit of its removal from the window as'occasion may require.

The screen illustrated comprises a fixed section 1 and a movable section 2 and may be oi any approved construction, the section 2 being slidable and held to'the section 1 in The operating means comprises a pivoted member 3 .and a link 1, the member 3being pivoted to the section 1 and the link 4. forming connecting. means between the pivoted member and the section 2 For convenience,

the pivoted member 3 is shown as consisting of an approximately U-shaped frame having the extremities of the side members connected by. means of a handle 5. A bar 6 constitutes supporting means for the pivoted member 3 and this'bar connects opposite members of the screen frame. The bar 6 as well as the link 14 may comprise sections which are adjustably connected to provide foradaptingthe operating mechanism to screens of difl'erent sizes. Sections 7 slidably engage l0ops8 at the ends of the bar 6 section 10 comprising the link connection is provided at one end with a loop 11 to receivethe inner section of the link, a clamp screw 12 securing the section 10 in the required adjusted position. that the member 3 is pivoted intermediate its ends tothe supporting bar 6, and that the link 4 is pivotally connected at its inner end to an end of tliemember 3, whereby a pivotal movement of the member actuates thelink 4 111 a manner to move the section 2 ofthe screen in or out,as desired; In the preferable arrangement theoperating mechanism is centrally disposed between the upper and lower'i'rame members of the screen,

locking means consist of a latch 13 pivoted at one end to an end of the member 3, a

finger piece 14 projecting. from the latch 13 and a springl5, the latter normally exerting Ya pressure to hold the latch 13 in operative position.- An opening 16 is formed in the It is observed supporting ba1 6 to receive the end of the latch 13, when the section 2 is moved inward. An opening 17 formed in the link 4 receives the end of the latch 13 when the section 2 is extended to hold the same projected. The

latch is conveniently positioned to admit of its engagement by the thumb of the hand grasping the handle 5 of the pivoted memher 3, so that the lock mechanism and the operating mechanism may be manipulated at thesame time by one hand.

In the modification shown in Figure 3, the supporting bar 6 and the link l may be of a determinate length to suit a fly screen of determinate size, and the lock mechanism is dispensed with since the parts are positioned to admit of the link l and member 3 alining when the movable section of the screen is projected to the limit of its movement. In this position, the pivot connection of the member 3 with the bar 6, the pivot connec tion of the link 4 with the member 3 and the pivot connection of the link with the movable section of the screen will lie in the same straight line, thereby forming a lock joint to hold the screen extended, as will be readily understood. Y

When applying the operating mechanism to a fly screen of the type embodying sliding sections, the latter are extended so as to lit the window for which the screen is intended.

The operating mechanism is next placed in position upon or against aside of the screen with the pivoted operating member 3 perpcndicular to the supporting bar 6 and when so adjusted the outer end of the link l is secured to the end bar of the adjustable screen section, and the ends of the supporting bar 6 are made last to opposite frame members of the fixed screen section 1. WVhen the operating mechanism is properly applied, the pivoted operating member 3 occupies an approximate central position of the screen and constitutes a handle by means of which the screen may be manipulated when placing it in position, or. removing it from a window.

When the member 3 occupies a position parallel with the supporting bar 6 the movable section of the screen is drawn inward. lVhen applying the screen to a window having a non-counterbalanced sash, the latter may be raised and held in position by one hand, while at the same time, the other hand grasps the operating member 3 and places the screen in position, after which the memher 3 is given a one-quarter turn to project the adjustable screen section 2 whereby to engage opposite ends of the screen in the ways in which the sash slides. After the screen has been positioned the sash is lowered so as to rest thereon. hen it is re 'q'uircd to remove the screen from the window, one hand is engaged in lifting the sash resting upon the screen and holding the sash elevated, while the other hand grasps the handle of the pivoted operating member and turns the same to withdraw the adjustable screen section, after which the screen may be readily removed from the window, as will be readily appreciated. It will thus be understood that a liy screen embodying the invention may be readily manipulated by one hand, the other hand being free to be occupiedin control ot a sash oi' the window,

ably secure the handle in a set position with the screen adjusted.

2. Operating mechanism for an extensible sereencomprising 'a support adapted to be secured to one section oi a screen in a vertical position, a handle consisting of a shaped bracket secured to said support with its arms projecting outwardly therefrom and a hand grip between the outer ends of the arms, a link having one end pivoted to said handle adjacent one arm and its other end adapted to be pivotally connected with another section of the screen, and a latch to releasabiy retain the handle in a set position carried by one arm of the handle. j

Operating mechanism for an extentsible screen comprising a support adapted to be secured to one section of a screenin a We tical position, a handle consisting of a U-shaped bracket secured to said support with its arms projectingoutwardly therefrom and a hand grip between the outer ends otthe arms, and a link having one end pivoted to said handle adjacent one arm thereof and its other end adapted to be pivotally connected with another section of the screen whereby the screen sections may be moved relative to each other when the handle is turned.

4. Operating "means for an extensible screen havingsections slidable transversely of each other, said operating means comprising a support having an intermediate section and end sections adjustably connected with the intermediate section and adapt'edto be secured to upper and lower portions of one screen section with thesuppo rt disposed vertically thereof, a handle pivoted to the intermediate section of said support intermediate the length thereof, and a link having sections adjustable longitudinally of each other, one section having its outer end pivoted to said handle and the other having its outer end adapted to be pivotally connecte with the other section of the screen.

5. Operating means for an extensible screen having sections slidable transversely of each other, said operating means comprising a support adapted to be secured in a vertical position adjacent the inner end of one screen section, a handle having a U-shaped body pivoted to said support with its arms extending outwardly from the supa tooth projecting from the inner end of the arm and engageable with the support to releasably hold the handle in a set position,

and a link pivoted atone end to said handle adjacent one arm thereof and having its other end adapted to be pivotally connected with the outer end portion of the other 2 screen section. I
